Abstract
A simple and easy laboratory protocol for the determination of the pKa of mono, di and tri-basic weak acids is described in this paper by using arbitrarily simulated data as a function of pH. An equation compatible to Kaleidagraph program is derived and used in the program to determine the pKa. The present protocol for the determination of the pKa is useful in teaching chemistry experiments in a Physical-Organic Chemistry Laboratory.
